Description

We present a novel implementation of the STA model, called STAR (STA-Revised), which was written from scratch. The model is based on the theory of Bar-Shalom and Oreg [1] with various improvements. A comparison with other atomic codes was performed and a good agreement was reached. The model is used to calculate and analyze solar opacities. We also implemented a model for the solution of the HNC equations for the calculation of ion-correlation functions for mixtures. We present first calculations of ion-correlation functions for the solar mixture in the solar center and near the convection zone base. These calculations will be used in the future to estimate the effect of the ionic structure of the plasma, on the calculation of solar opacities. [1] Bar-Shalom, A., et al.
